Product Overview
The TR4 Metal Roofing Panel Roll Forming Machine is a high-precision engineering solution designed specifically for producing trapezoidal roof panels with 4 to 6 ribs. Engineered for versatility, the TR4 profile is an industry standard for industrial buildings and architectural projects, offering the unique capability to create curved panels for sophisticated structural designs. We provide a comprehensive package solution that integrates the TR4 forming machine with an optional hydraulic curving machine to meet diverse construction needs.
Our equipment is meticulously crafted to transform PPGI, PPGL, and GI coils into high-strength roofing sheets. With a focus on structural integrity and precision, the machine utilizes a separate rolling design concept to release internal sheet stress, ensuring the final product maintains a perfect shape and high dimensional accuracy. Whether for industrial warehouses, hotels, or modern residential villas, this machine delivers a classical appearance with professional-grade durability.

Frequently Asked Questions
Yes, TR4 panels are ideal for curved designs. We offer a complete package including the roll forming machine and a specialized hydraulic curving machine to achieve the desired arc.
The machine is designed to work with high-quality PPGI (Pre-painted Galvanized), PPGL (Pre-painted Galvalume), and GI (Galvanized) steel coils.
Absolutely. While we provide standard profiles like the Peru TR4 (40mm height), we can customize the rollers and machine settings according to your specific technical drawings.
We use a hydraulic pillar-type cutting system controlled by a Delta PLC and inverter, allowing for highly accurate length-set cutting and minimal waste.
Separate rolling prevents the accumulation of internal stress in the metal sheet during forming, which eliminates warping and ensures the panels are perfectly straight and high-precision.
Longway provides a 2-year free warranty and lifetime after-sale technical support, ensuring your equipment operates at peak performance throughout its lifecycle.
